Wearing or decorated with ruffles, or adorned with a ruff (a stiff collar or neck frill).
From the prefix 'be-' (meaning to cover or surround) combined with 'ruff,' referring to the pleated collar fashionable in Renaissance times.
The ruff was such an outrageous fashion statement in Elizabethan times that it required hours to style and entire servants to maintain it—imagine getting dressed taking longer than school!
